'1 01m (Cl. 116-129) This application is a continuation in part of application No. 97,247, filed August 21, 1936.

This invention relates to weighing apparatus andhas for its object to provide improved means I for accurately and instantaneously setting indicating, printing and like means in dependence on the position of equilibrium of the weighing apparatus. 7

A further object is to provide an,- arrangement of this character in which feeler members are caused to cooperate with a perforated member to effect the setting of the indicating or printing means, one of said members being initially actuated by the weighing apparatus in degree proportional to the extent of movement of-the weigh.- ing apparatus incident to a weighing operation.

In the accompanying drawings wherein several embodiments of the invention are illustrated.

Figure 1 is a diagrammatic view of a weighing apparatus illustrating the invention applied thereto. i

' Fig. 2 is an enlarged fragmentary front eleva- 7 tion of the pointer and dial showing the construction and arrangement of the perforated member, the feeler members and related parts being removed Fig. 3. is a sectional view taken radially through the dial and perforated member and showing the feeler members and printing or indicating means in top plan.

Fig. 4 is a front elevation of a modification of the invention.

Fig. 5 is a side view of Fig. 4. z i 7 Figs. 6 and 7 are enlarged detail views showing different forms of perforated members' Referring to meral I indicates the fulcrum of a weighing beam '2 which is pivotally connected at 5 to a rod 5a supporting the weighing platform 4. The lower end of the rod 5a pivotally connected to a link 6 which is pivoted at 1 to a suitable support adjacent the fulcrum l of the beam 2, the rod 5a and link 6 serving to maintain the weighing platform 4 in a-horizontal position.

The end of thebeam 2 opposite the fulcrum i is connected by a strap IS with a pendulum weight I4 and a suitable type of check I! for damping thefoscillating movement of the beam M thereon for cooperation "the stationary the drawings in detail, the nupointer I2 for indicating the weight of the article 3 placed upon the platform 4.

The dial In which in thisform of the invention is in theshape of a disk, carries the perforated member ii. The dialis provided with 1000 graduations for weighing articles up to and including 1000 grams and the fragment thereof shown in Fig. 2 represents that part ranging from 550 to 614 grams.

The perforated member I5 is divided radially into three denominational zones indicated inFig. 2 as hundreds, tens and units. The perforations in the member ii are so arranged that in every position of the dial i0 a number of perforations.

corresponding to the number of units of weight indicated by the dial I0 is disposed in the position indicated by the.broken line H in Fig. 2.

Three feeler members I11, I'I1o, and 11100 are arranged in front of the groups of units, tens and hundreds perforations in the disk I 6 along 'the line aa. Each feeler member includes a group of nine pins having pointed ends terminating in stepped relation and adapted to successively enter the perforations of the disk ii which are presented thereto in the position of adjustment of the dial i0. Owing to the gradu ated length of the feeler pins the extent of movefeeler pins may enter therein and said feeler member may thereby perform a full stroke corresponding to the value 9.'

The feeler members H to are attached to rectangular'bars II which are suitably mounted for longitudinal sliding movement. The under sides of the bars I! are provided with teeth meshmg with pinions 2| to which numeral wheels 22 are secured.- The numeral wheels 22 are provided on. the circumference thereof with numerals ranging from Oto 9 which may be arranged for visibleinspection or may be in the form of printing type for printing purposes.

The bars I. together with the related feeler members II are normally urged toward the perforated member I by springs 23 arranged between the suitable abutment 24 and pins 20 fixed to the bars ll. The bars I! are held in re- 'tracted position against the tension of the springs 23 by a stop bar I! pivotally supported by arms whereby .thebar may be raised to disengage it from the pins 29 and thereby permitthe ieeler members to move toward the perforated member ifi'under the influence oi the springs 23.

Assuming that an article weighing 578 grams 1 is placed on the platform l, when the weighing apparatus arrives at the equilibrium position; the

pointer it will indicate that value on the dial ill and flveof the hundreds perforations will be presented to the feeler member Elmo, seven of the tens perforations will be presented to the ieeler members Hm and eight perforations of the units group will be presented to the ieel'er member ill.

the toothed connection between thebars id and the pinions 2i and the several numeral wheels, from left to right are moved to such extent as to indicate respectively, the values 5", '7 and 8.

The periorated member is is provided with an additional set of perforations 28, one located at every position of the dial it. Tl'lese perforations 26 are of conical form and are" arranged with the large ends thereof adjacent a positioning pin 21 attached to the unit ieeler member ill. The pin 21 is of greater length than them of the feeler members i! and consequently it enters one of the'perforations 26 in advance of the penetration by the pins of the feeler members ill and thereby initially positions the perforated memher It in accurate registration with the pins.

In the modification of the invention illustrated in Figures 4 and tithe platform. 8a supported by a. lever to which is mounted to turn about a fulcrum 3| and is provided at the end opposite the fulcrum with a gear segment 32 meshing -with a pinion 33.; .The pinion 33 is fixed to the hundreds, tens and units perforations are formed in the circumference thereof; Three ieeler members Ila provided'with-a group of pointed pins as above described in connection with figs. l to 3 are arranged below the perforated member 56. Each feeler member We is attached to a bar Ma mounted for vertical movement in the frame 46 and provided with rack teeth engaging pinions 5.

The pinion d5 cooperating with the units feelermember is fixed to a shaft d5 journaled in the frame All and provided at its opposite end with a n numeral wheel M. The pinions d5 cooperating with the tens, hundreds ieeler members We are lined to tubular shafts do and or arranged for relative rotation upon the shaft to and respectively provided with numeral wheels so and 5!. Each of the bars 18a is subjected to the tension of a spring 57 whereby the several bars together with the feeler members carried thereby are normally urged upwardly. The lower extremities of the bars a are provided with pins 52 which are engaged by one end of a retracting lever 53 pivotally mounted at 54 in the frame 85,! and prosion of which is sumcient to overcome the combined tension of the several springs 5'5 and thereby maintain the several feeler. members ila in inoperative position. 4

The numeral wheels ll, so and 55 are provided with peripheral printing type which are set-in dependence upon the position of the :Eeeler members illt. Rollers 53 and 55 are journaled in the frame ll) and support a carbon strip 60 :ior making a legible impression upon the paper strip 58 on depression of the stamp e2. The paper strip Bi is wound on the roller 53 supthe carbon strip 69 and a cutting blade t l is provided for severing a part of the strip iii after an impression has been made thereon. The stamp 62 is normally held in elevated inoperative position by spring 65 cooperating with a manually operable handle 55 mounted for vertical slidin movement in the frame it.

In operation, the weight of the article placed on the platform to causes displacement of the dial 36 together with the perforated member M to a position corresponding to the units of weight.

When the weighing mechanism attains its posiported in the machine frame and extending across tent depending upon the number of perforations v inthe member'fild which are presented to the severa! groups of pins. The movement of the bars ldafis transmitted to the pinlons 55 which turn the number wheels ll, 59 and hi to positions in which. the number types corresponding to the value of the weight units of the article placed,

on theplatform to are disposed immediately under the paper strip (it, While still retaining the handle so in depressed position, the handle so is depressed against the tension of the spring 65 and the pressure exerted by the stamp 52 produces an impression of the'type of the wheels il, 58 and 5! through the medium of the carbon strip 5i]. After the release of the handle til the handle so is also released and the tension of the spring 56 restores the rods lea, feel members Ho and numeral wheels dl, lid and 55 to their original position.

Although it is assumed in the above description that the feeler members move at right angles to the surface of the periorated member, it will be understood that the angular relation may be varied and it is also possible that the several feeler members may befrlisplaced in relation to each other or disposed at an inclination, that is to say, alongthe line of a helix of the perfober movable in degree proportional to the setting of the weighing apparatus, independently displaceable feeler members, said perforated member having perforations thereinarranged in groups of difierent denominational values adapted to be presented to sai d ieeler members dur' ing movement of. the perforated member, the number of perforations oi the several groups presented to said feeler members, in every position of the perforated member-corresponding to the number of units of weight of the goods being weighed, each of said feeler members including a group of pins corresponding to each group of perforations and adapted during displacement to penetrate said perforations to a degree proportional to the number of perforations presented thereto.
